     TEXT: EXTRACT.
     THE MODEL TDN-1 FOUR WIRE CEREBRAL BIOELECTRICAL SOURCE ELECTRODE
     CAP WAS DEVELOPED FOR RECORDING HUMAN CEREBRAL BIOELECTRICITY UNDER
     SOME SPECIAL CONDITIONS. THE ELECTRODE CAP HAS RELATIVELY HIGH
     NOISE IMMUNITY AND CAN BETTER RECORD HUMAN BIOELECTRICAL SIGNALS
     DURING SOME MOVING STATES. AS PROVED FOLLOWING LONG PERIODS OF
     ACTUAL USE, THE INSTRUMENT CAN ACCURATELY AND CLEARLY RECORD
     VARIATIONS OF HUMAN CEREBRAL BIOELECTRICITY UNDER CONDITIONS OF LOW
     ATMOSPHERE PRESSURE WITH OXYGEN DEFICIENCY, QIGONG (GAS ENERGY)
     MEDITATION STATE, AND,FIELD EXPERIMENTAL CONDITIONS WITH RELATIVELY
     HIGH INTERFERENCE. THUS, THESE ELECTRODE CAPS HAVE GOOD COMMENTS
     FROM USERS. IN ADDITION, IF A SMALL MAGNETIC TAPE RECORDER OR A
     TRANSMITTER is ATTACHED TO THE INSTRUMENT, HUMAN CEREBRAL
     BIOELECTRICITY DURING FREE MOVING CONDITIONS CAN ALSO BE RECORDED.
     THUS, THIS IS A VERY FEASIBLE INSTRUMENT FOR RECORDING CEREBRAL
     BIOELECTRICITY FOR PROLONGED CLINICAL MONITORING OF PATIENTS AS WELL
     AS ATHLETIC ACTIVITIES.
